when find or replace at regex, such as ^$\r\n， The newline symbol at the end of the line cannot be recognized. If you want to replace these characters, you will fail. It's not a good idea。

Sci::Position BuiltinRegex::FindText(Document *doc, Sci::Position minPos, Sci::Position maxPos, const char *s,

......
Sci::Position startOfLine = doc->LineStart(line);
Sci::Position endOfLine = doc->LineEnd(line); ------->myabe to change with LineStart(line+1)
